My IR reciever blew off when i gave 5v from the board.Plz change the value to 3.3v if not someone less will also face the trouble too.

Hi Sara,

I followed your instructions to download the ‘Ir Remote’ library.

When I got the result shown above I did some research. Went onto Arduino forum & found a solution.

Then I modified your code as shown below. The decoded values for numbers 1 – 6 are 0 -5.

This I used in the switch statement.

The code now works perfectly.

But why:

(1) Did the original code not work on my system.

(2) Why do I now get single digit codes?

Keep up your great work.

Stay safe

Alan

#include

const byte IR_RECEIVE_PIN = 11;
int IrReceiverValue;
int bluePin = 10;
int greenPin = 9;
int yellowPin = 8;

void setup(){
Serial.begin(9600); //starts serial communication
IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK);

pinMode(bluePin, OUTPUT); // sets the digital pin as output
pinMode(greenPin, OUTPUT); // sets the digital pin as output
pinMode(yellowPin, OUTPUT); // sets the digital pin as output
}

void loop(){
//decodes the infrared input
if (IrReceiver.decode()){
IrReceiverValue = IrReceiver.decodedIRData.command, HEX;

//switch case to use the selected remote control button switch (IrReceiverValue){ case 0: //when you press the 1 button digitalWrite(bluePin, HIGH); break; case 1: //when you press the 4 button digitalWrite(bluePin, LOW); break; case 2: //when you press the 2 button digitalWrite(greenPin, HIGH); break; case 3: //when you press the 5 button digitalWrite(greenPin, LOW); break; case 4: //when you press the 3 button digitalWrite(yellowPin, HIGH); break; case 5: //when you press the 6 button digitalWrite(yellowPin, LOW); break; } IrReceiver.resume(); // Receives the next value from the button you press

}
delay(10);

Sara,

All I get when running the sketch in this tutorial is:

The function decode(&results)) is deprecated and may not work as expected! Just use decode() – without any parameter.

checked wiring, OK.
used decode(): monitor completely blank.

Please help.

Do you have any tutorials like this for the esp8266?

Thanks

I followed exactly what you did and controlled the LED using my arduino board first time. it is so simple. Thank you so much. Keep helping us.

I followed this tutorial, there were compile errors referred to the file IRremote.cpp. I did the corrections and there were no errors. I checked with NEC, panasonic and another (Sky). How can we know the format of the IR code from this sketch. I added another Serial.print to output the decimal value.

Thanks for that suggestion.
That’s definitely an easier way to do the same thing.
Thank you
